Auto-assign Values Of Different Objects One To Each Other?
Mar 2, 2010
I'm new in this forum. I am also quite a rookie programming in VB2008. In fact I'm not even a professional programmer. The situation is as follows.
I was hired by a company to do an Industrial Engineering job, but after some time, I realized that my job was also to design a database manager in VB2008 for the train wheel stock. So I am terribly lost. My problem here is that I dont know how to compare values and assign the biggest with the biggest, the smallest with the smallest etc. So I want to create a table and auto-arrange the values. An example of what I want to do in a macro of Excel is[code]...

Public Property Prop1 As String
Public Property Prop2 As String[code]....
But it is not working as I expect it to. You can see it from.The DtlsB properties of all three DtlsA objects are having values from last iteration.

Probably a simple question for most of you. I'm putting members of a group into a SQL Database so we can better manage attendance and 'points' that they earn for doing work. I've written the program in VB and have the SQL server running fine. However, I have created a separate table to handle the points and have marked the relationship between the table - the column is named 'PointID', and should be unique for each person. When I add a new user to the database, I want it to automatically assign a value to that without me having to do anything extra beyond pressing save. From this PointID, it should identify the user and it will bring up the person's points.

I have a label, lblmessage, which I want to assign 4 different values. It should show up like this:
[Code]...
I know this: lblmessage.text = "5" and to assign it another value lblmessage.text = lblmessage.text + "4". This just puts them next to each other, but how can I get them to show up underneath each other?

This feels like a completely basic question, but, for the life of me, I can't seem to work out an elegant solution.
Basically, I am doing a LINQ query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example).
Here is my current solution that does what I need:
Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _
Order By x.Key _
Select New With {.CalendarId = x.Key, .Iter = 0}
[Code]....
Is there a way to do this within the context of the LINQ query (so that I don't have to loop the collection after the query)?

I have a user defined structure in a list that I am trying to change the value for in an individual element within the list of structures. Accessing the element is not a problem. However, the compiler complains
"Expression is a value and therefore cannot be the target of the assignment"when I try to update the value.For example:
Public Structure Person
Dim first as String
Dim last as String
Dim age as Integer

I am working on simple handover process from one mobile station to other. I got three proposed results service disruption time, network entry time, connection set up time. I also have the result of these three as by using some conventional way and got improved these three delay results by proposed way.
Results are store in textboxes. Now i want to show graphically. E.g. I want to show conventional service disruption time on x axis and proposed service disruption time on y axis or vice versa. Let suppose I want to have a scale on axes from 1 to 3000 milliseconds. Then I want to show how purposed scheme is better. I am using VB.Net 2008

I also studied MS chart for windows forms samples environment. Also applied different chart properties like titles, series and others, But I am not able to make x and y axes scales. How to get values on the axes and how to generate graph? [code]
A chart element with the name '0' could not be found in the 'ChartAreaCollection'.i also tried using ChartAreas(Default") but i am getting same idea.I don't get what for this chartAreas value in parenthesis is used.

After user entered a value into textbox (for example 4), datargidview must be create automatically(number of datargidview's columns and rows must be textbox value). And, user enter some values that among 0 and 1 into datagridview's cells. So i want to assing these values (values that are written in datgridview cells). For example, if user enter 0.25 in datagridview's cell 1, and 0.34 cell 2, 0.67 cell 3, and etc, in this instance array(1,1)=0.25, array(1,2)=0.34, array(1,3)=0.67 must be assigned. i hope, i could understand :) i illustrate this example below. i want to assign such as indexs that is written into following example table.

I'm building a virtual blackjack game and I'm having difficulty assigning values to the cards. I've set up picture boxes for the dealer's cards and the player's cards, and i've linked those picture boxes to an ImageList that contains all of the cards (+ the picture of the back of the card, since you only see one of the dealer's cards to start out with). When you hit the "Deal" button, I have the following code so far:
Private Sub btnDeal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeal.Click
Me.btnHit.Visible = True
Me.btnHit.Enabled = True
I have a section at the top that has labels saying: "Dealer's Showing ______", "You're Showing ________"how to assign values to the indexes/items of the imagelist? For example, items 0-3 have a value of "2", items 4-7 has a value of "3", and so forth...

I have a VB.net form which has two webpages embedded. The webpages have a 5 second auto refresh built into the HTML header as the information is constantly changing.
The problem I have is when I pull up a secondary form, I lose focus to the 'Main' form everytime the webpage refreshes.
Is there any way to stop the webpages autorefreshing in the form and I will build in a refresh command into a timer I already have in place and then I can start and stop the refresh at will.
Unfortunatly I cannot amend the source code of the HTML as this is required for a different process elsewhere.
